The dip happened probably due to the situation regarding the Silk Road, so there is that.
And I agree - we need a bit more time after the inauguration to see the effects of some promises that were made being acted upon. Otherwise, the sentiment would remain at the same level it is now.
Now, there has been another drop in Bitcoin and also in almost all other altcoins. I was even surprised when I saw Bitcoin which was at $93K fell to $90K today and I don't know what sentiment is there towards the market that can cause a price correction in Bitcoin and also others to happen so suddenly like now. I am also waiting for Donald Trump's inauguration because I also want to see how the market conditions move after that event is over. But today alone we all have witnessed something unpleasant in the Bitcoin price.
